Technology that optimises water distribution networks

THE IMPORTANCE OF OPTIMISING WATER PRESSURE

PRESSURE MANAGEMENT CHALLENGE

BASIC PRESSURE MANAGEMENT

+ Fixing pressure at the PRV outlet

+ Leads to excessive pressure 100% of the time at critical point

+ Potential response: basic time & flow modulation

+ Weak control of pressure vs target

+ Inability to respond and adapt to changing network circumstances

ADVANCED PRESSURE MANAGEMENT

+ Total visibility into network performance

+ Remote management of pressure

+ Automatically and continuously optimised pressure based on demand patterns

+ Delivers the right pressure (and no more) in the network all the time

LEAKAGEREDUCTION

+ Each percentage point of pressure reduction in a water network leads to a corresponding decrease in leakage

+ i2O’s solutions have reduced leakage by 10 to 50% in hundreds of water networks.

Syabas: 35.4 MLD reduction in 178 DMAs

BURSTFREQUENCYREDUCTION

After i2OBefore i2O

+Minimizing pressure peaks and softening fluctuations reduces the frequency of bursts

+ i2O’s solutions have reduced burst frequency by 40% or more in customers’ water networks.

LOWEROPERATINGCOSTS

+ Remote monitoring gives managers visibility to network performance and events from any online connection or location

+ Remote PRV control eliminates site visits to adjust PRVs manually

+ Reduced leakage and bursts decrease need for ‘find and fix’ activity

+ Early detection of asset degradation reduces need for routine maintenance visits

IMPROVEDCUSTOMERSERVICE LEVELS

+Many water networks’ service levels suffer during peak demand, leading to complaints and fines.

+ i2O’s solutions maintain the right pressure, without abrupt changes, minimising customer service problems.

ENERGYSAVINGS

+ The lower the water pressure you supply to a network, the lower your energy consumption

+ Installed on pumps with variable speed drives, Advanced Pressure Management from i2O can reduce energy consumption by more than 20%

EXTENDEDMAINSLIFETIMES

+Many water networks are at or near their service lifetimes

+ Burst frequency is the key trigger for capital-intensive pipe replacement investments

+ Reduced burst frequency significantly extends pipe lifetimes
